This is all based on highly subjective impressions of course, but in my experience the problem with SV drivers is the opposite of what you're insinuating. If there's a stereotypical SV driver, it's someone who is mellow to the point of endangering everyone else on the road- merging onto 65 MPH freeways at 30 MPH, putzing along in the fast lane going well below the speed limit, not using turn signals, rolling up to stoplights and stopping multiple car lengths behind the car in front of them, screwing around with their phones while driving, and just generally being very lackadaisical, careless, impolite, and unaware of what's going on around them. The drivers tend to be nonaggressive, unaware, and pokey to the point of being a source of actual danger to others.
